BACKGROUND OF THE INVENTION

This invention relates to certain ortho-substituted aryl amides, their N-oxides, salts and compositions suitable for agronomic and nonagronomic uses, including those listed below, and methods of their use for controlling invertebrate pests in both agronomic and nonagronomic environments.

The control of invertebrate pests is extremely important in achieving high crop efficiency. Damage by invertebrate pests to growing and stored agronomic crops can cause significant reduction in productivity and thereby result in increased costs to the consumer. The control of invertebrate pests in forestry, greenhouse crops, ornamentals, nursery crops, stored food and fiber products, livestock, household, and public and animal health is also important. Many products are commercially available for these purposes, but the need continues for new compounds that are more effective, less costly, less toxic, environmentally safer or have different modes of action.

DETAILS OF THE INVENTION

In the above recitations, “alkyl”, used either alone or in compound words such as “alkylthio” or “haloalkyl” includes straight-chain or branched alkyl, such as methyl, ethyl, n-propyl, i-propyl, or the different butyl, pentyl or hexyl isomers. “Alkenyl” includes straight-chain or branched alkenes such as 1-propenyl, 2-propenyl, and the different butenyl, pentenyl and hexenyl isomers. “Alkenyl” also includes polyenes such as 1,2-propadienyl and 2,4-hexadienyl. “Alkynyl” includes straight-chain or branched alkynes such as 1-propynyl, 2-propynyl and the different butynyl, pentynyl and hexynyl isomers. “Alkynyl” can also include moieties comprised of multiple triple bonds such as 2,5-hexadiynyl. “Alkoxy” includes, for example, methoxy, ethoxy, n-propyloxy, isopropyloxy and the different butoxy, pentoxy and hexyloxy isomers. “Alkylthio” includes branched or straight-chain alkylthio moieties such as methylthio, ethylthio, and the different propylthio and butylthio isomers. “Cycloalkyl” includes, for example, cyclopropyl, cyclobutyl, cyclopentyl and cyclohexyl. “Trialkylsilyl” includes (CH₃)₃Si, (CH₃CH₂)₃Si and [(CH₃)₃C](CH₃)₂Si.

The term “aromatic” indicates that each of the ring atoms is essentially in the same plane and has a p-orbital perpendicular to the ring plane, and in which (4n+2) π electrons, when n is 0 or a positive integer, are associated with the ring to comply with Hückel's rule. The term “aromatic ring system” denotes fully unsaturated carbocycles and heterocycles in which at least one ring of a polycyclic ring system is aromatic. Aromatic carbocyclic rings or fused carbobicyclic ring systems includes fully aromatic carbocycles and carbocycles in which at least one ring of a polycyclic ring system is aromatic (e.g. phenyl, naphthyl and 1,2,3,4-tetrahydro-naphthyl). The term “nonaromatic carbocyclic ring” denotes fully saturated carbocycles as well as partially or fully unsaturated carbocycles where the Hückel rule is not satisfied by the ring. The term “hetero” in connection with rings or ring systems refers to a ring or ring system in which at least one ring atom is not carbon and which can contain 1 to 4 heteroatoms independently selected from the group consisting of nitrogen, oxygen and sulfur, provided that each ring contains no more than 4 nitrogens, no more than 2 oxygens and no more than 2 sulfurs. The terms “heteroaromatic ling or ring system” and “aromatic fused heterobicyclic ring system” includes fully aromatic heterocycles and heterocycles in which at least one ring of a polycyclic ring system is aromatic (where aromatic indicates that the Hückel rule is satisfied). The term “nonaromatic heterocyclic ring or ring system” denotes fully saturated heterocycles as well as partially or fully unsaturated heterocycles where the Hückel rule is not satisfied by any of the rings in the ring system. The heterocyclic ring or ring system can be attached through any available carbon or nitrogen by replacement of a hydrogen on said carbon or nitrogen.

The term “halogen”, either alone or in compound words such as “haloalkyl”, includes fluorine, chlorine, bromine or iodine. Further, when used in compound words such as “haloalkyl”, said alkyl may be partially or fully substituted with halogen atoms which may be the same or different. Examples of “haloalkyl” include F₃C, ClCH₂, CF₃CH₂ and CF₃CCl₂. The terms “haloalkenyl”, “haloalkynyl”, “haloalkoxy”, and the like, are defined analogously to the term “haloalkyl”. Examples of “haloalkenyl” include (Cl)₂C═CHCH₂ and CF₃CH₂CH═CHCH₂. Examples of “haloalkynyl” include HC≡CCHCl, CF₃C≡C, CCl₃C≡C and FCH₂C≡CCH₂. Examples of “haloalkoxy” include CF₃O, CCl₃CH₂O, HCF₂CH₂CH₂O and CF₃CH₂O.

Examples of “alkylcarbonyl” include C(O)CH₃, C(O)CH₂CH₂CH₃ and C(O)CH(CH₃)₂. Examples of “alkoxycarbonyl” include CH₃OC(═O), CH₃CH₂OC(═O), CH₃CH₉CH₂OC(═O), (CH₃)₂CHOC(═O) and the different butoxy- or pentoxycarbonyl isomers. Examples of “alkylaminocarbonyl” include CH₃NHC(═O), CH₃CH₂NHC(═O), CH₃CH₂CH₂NHC(═O), (CH₃)₂CHNHC(═O) and the different butylamino- or pentylaminocarbonyl isomers. Examples of “dialkylaminocarbonyl” include (CH₃)₂NC(═O), (CH₃CH₂)₂NC(═O), CH₃CH₂(CH₃)NC(═O), CH₃CH₂CH₂(CH₃)NC(═O) and (CH₃)₂CHN(CH3)C(═O).

The total number of carbon atoms in a substituent group is indicated by the “C_(i)-C_(j)” prefix where i and j are integers from 1 to 8. For example, C₁-C₃ alkylsulfonyl designates methylsulfonyl through propylsulfonyl; C₂ alkoxyalkyl designates CH₃OCH₂; C₃ alkoxyalkyl designates, for example, CH₃CH(OCH₃), CH₃OCH₂CH₂ or CH₃CH₂OCH₂; and C₄ alkoxyalkyl designates the various isomers of an alkyl group substituted with an alkoxy group containing a total of four carbon atoms, examples including CH₃CH₂CH₂OCH₂ and CH₃CH₂OCH₂CH₂.

In the above recitations, when a compound of Formula I contains a heterocyclic ring, all substituents are attached to this ring through any available carbon or nitrogen by replacement of a hydrogen on said carbon or nitrogen.

When a compound is substituted with a substituent bearing a subscript that indicates the number of said substituents can exceed 1, said substituents (when they exceed 1) are independently selected from the group of defined substituents. Further, when the subscript indicates a range, e.g. (R)_(i-j), then the number of substituents may be selected from the integers between i and j inclusive.

The term “optionally substituted” indicates that the group is either unsubstituted or substituted. The term “optionally substituted with from one to three substituents” and the like indicates that from one to three of the available positions on the group may be substituted. When a group contains a substituent which can be hydrogen, for example R¹ or R⁵, then, when this substituent is taken as hydrogen, it is recognized that this is equivalent to said group being unsubstituted.

Compounds of this invention can exist as one or more stereoisomers. The various stereoisomers include enantiomers, diastereomers, atropisomers and geometric isomers. One skilled in the art will appreciate that one stereoisomer may be more active and/or may exhibit beneficial effects when enriched relative to the other stereoisomer(s) or when separated from the other stereoisomer(s). Additionally, the skilled artisan knows how to separate, enrich, and/or to selectively prepare said stereoisomers. Accordingly, the compounds of the invention may be present as a mixture of stereoisomers, individual stereoisomers, or as an optically active form. Some compounds of this invention can exist as one or more tautomers, and all tautomeric forms of such compounds are part of the present invention. Accordingly, the compounds of the invention may be present as a mixture of tautomers or the individual tautomers.

The present invention comprises compounds selected from Formula I, N-oxides and suitable salts thereof. One skilled in the art will appreciate that not all nitrogen containing heterocycles can form N-oxides since the nitrogen requires an available lone pair of electrons for oxidation to the oxide; one skilled in the art will recognize those nitrogen containing heterocycles which can form N-oxides. One skilled in the art will also recognize that tertiary amines can form N-oxides. Synthetic methods for the preparation of N-oxides of heterocycles and tertiary amines are very well known by one skilled in the art including the oxidation of heterocycles and tertiary amines with peroxy acids such as peracetic and in-chloroperbenzoic acid (MCPBA), hydrogen peroxide, alkyl hydroperoxides such as t-butyl hydroperoxide, sodium perborate, and dioxiranes such as dimethydioxirane. These methods for the preparation of N-oxides have been extensively described and reviewed in the literature, see for example: T. L. Gilchrist in Comprehensive Organic Synthesis, vol. 7, pp 748-750, S. V. Ley, Ed., Pergamon Press; M. Tisler and B. Stanovnik in Comprehensive Heterocyclic Chemistry, Vol. 3, pp 18-19, A. J. Boulton and A. McKillop, Eds., Pergamon Press; M. R. Grimmett and B. R. T. Keene in Advances in Heterocyclic Chemistry, Vol. 43, pp 139-151, A. R. Katritzky, Ed., Academic Press; M. Tisler and B. Stanovnik in Advances in Heterocyclic Chemistry, Vol. 9, pp 285-291, A. R. Katritzky and A. J. Boulton, Eds., Academic Press; and G. W. H. Cheeseman and E. S. G. Werstiuk in Advances in Heterocyclic Chemistry, Vol. 22, pp 390-392, A. R. Katritzky and A. J. Boulton, Eds., Academic Press.

The salts of the compounds of the invention include acid-addition salts with inorganic or organic acids such as hydrobromic, hydrochloric, nitric, phosphoric, sulfuric, acetic, butyric, fumaric, lactic, maleic, malonic, oxalic, propionic, salicylic, tartaric, 4-toluenesulfonic or valeric acids. The salts of the compounds of the invention also include those formed with organic bases (e.g., pyridine, ammonia, or triethylamine) or inorganic bases (e.g., hydrides, hydroxides, or carbonates of sodium, potassium, lithium, calcium, magnesium or barium) when the compound contains an acidic group such as a carboxylic acid or phenol.

As noted above, each J is independently a phenyl ring, a 5- or 6-membered heteroaromatic ring or an aromatic 8-, 9- or 10-membered fused carbobicyclic or heterobicyclic ring system, wherein each ring or ring system is substituted with from one to four R⁵. An example of phenyl substituted with from one to four R⁵ is the ring illustrated as U-1 in Exhibit 1 below, wherein R^(v) is R⁵ and r is an integer from 1 to 4. Examples of aromatic 8-, 9- or 10-membered fused carbobicyclic ring system substituted with from one to four R⁵ include a naphthyl group illustrated as U-85 in Exhibit 1 and a 1,2,3,4-tetrahydronaphthyl group illustrated as U-89 in Exhibit 1, wherein R^(v) is R³ and r is an integer from 1 to 4 . Examples of 5- or 6-membered heteroaromatic rings substituted with from one to four R⁵ include the rings U-2 through U-53 illustrated in Exhibit 1 wherein R^(v) is R⁵ and r is an integer from 1 to 4. Note that J-1 through J-4 below also denote,5- or 6-membered heteroaromatic rings. Note that U-2 through U-20 are examples of J-1, U-21 through U-35 and U-40 are examples of J-2, U-41 through U-48 are examples of J-3 and U-49 through U-53 are examples of J-4. Examples of aromatic 8-, 9- or 10-membered fused heterobicyclic ring systems substituted with from one to four R⁵ include U-54 through U-84 illustrated in Exhibit 1 wherein R^(v) is R⁵ and r is an integer from 1 to 4.

Although R^(v) groups are shown in the structures U-1 through U-90, it is noted that when they are optional substituents they do not need to be present. Note that when R^(v) is H when attached to an atom, this is the same as if said atom is unsubstituted. The nitrogen atoms that require substitution to fill their valence are substituted with H or R^(v). Note that some U groups can only be substituted with less than 4 R^(v) groups (e.g. U-14, U-15, U-18 through U-21 and U-32 through U-34 can only be substituted with one R^(v)). Note that when the attachment point between (R^(v))_(r) and the U group is illustrated as floating, (R^(v))_(r) can be attached to any available carbon atom of the U group. Note that when the attachment point on the U group is illustrated as floating, the U group can be attached to the remainder of Formula I through any available carbon of the U group by replacement of a hydrogen atom.

Exhibit 1

As noted above, certain R¹, R³, R⁶ and R⁸ groups can be optionally substituted with one or more substituents. The term “optionally substituted” in connection with these R^(w) groups (wherein w is 1, 3, 6 or 8) refers to R groups that are unsubstituted or have at least one non-hydrogen substituent. Examples of optionally substituted R^(w) groups are those that are optionally substituted by replacement of a hydrogen on a carbon atom of the R^(w) group with one or more (up to the total number of hydrogens available for replacement in any specific R^(w) group) substituents independently selected from the substituents listed in the Summary of the Invention above. Although these substituents are listed, it is noted that they do not need to be present since they are optional substituents. Of particular note are R^(w) groups that are unsubstituted. Of note are R^(v) groups substituted with from one to five substituents. Also of note are R^(w) groups substituted with one substituent.

As noted above, each R⁶ and each R⁸ can be independently (among others) a phenyl ring or a 5- or 6-membered heteroaromatic ring, each ring optionally substituted with from one to three substituents independently selected from R⁹. Examples of such R⁶ each R⁸ groups include the rings illustrated as rings U-1 (phenyl) and U-2 through U-53 (5- or 6-membered heteroaromatic rings)illustrated in Exhibit 1 above, wherein R^(v) is R⁹ and r is an integer from 1 to 3.

One or more of the following methods and variations as described in Schemes 1-33 can be used to prepare the compounds of Formula I. The definitions of A, B, J, R¹, R², R³, R⁴, R⁵, R⁶, R⁷, R⁸, R⁹ and n in the compounds of Formulae 1-88 below are as defined above in the Summary of the Invention. Compounds of Formulae Ia-e, 2a-b, 4a-s, 5a-d are various subsets of the compounds of Formula I, 2, 4 and 5.

Compounds of Formula Ia (wherein K is NR¹C(═O)) can be prepared by coupling of an amine of Formula 2 with an acid chloride of Formula 3 in the presence of an acid scavenger to provide the compound of Formula Ia. Typical acid scavengers include amine bases such as triethylamine, diisopropylethylamine and pyridine; other scavengers include hydroxides such as sodium and potassium hydroxide and carbonates such as sodium carbonate and potassium carbonate. In certain instances it is useful to use polymer-supported acid scavengers such as polymer-bound diisopropylethylamine and polymer-bound dimethylaminopyridine. The coupling can be run in a suitable inert solvent such as tetrahydrofuran, dioxane, diethylether or dichloromethane to afford the anilide of Formula Ia. In a subsequent step, amides of Formula Ia can be converted to thioamides of Formula Ib using a variety of standard thio transfer reagents including phosphorus pentasulfide and Lawesson's reagent.

An alternate procedure for the preparation of compounds of Formula Ia involves coupling of an amine of Formula 2 with an acid of Formula 4 in the presence of a dehydrating agent such as dicyclohexylcarbodiimide (DCC). Polymer supported reagents are again useful here, such as polymer-bound cyclohexylcarbodiimide. Synthetic procedures of Schemes 1 and 2 are only representative examples of useful methods for the preparation of Formula I compounds as the synthetic literature is extensive for this type of reaction.

One skilled in the art will also realize that acid chlorides of Formula 3 may be prepared from acids of Formula 4 by numerous well-known methods. For example, acid chlorides of Formula 3 are readily made from carboxylic acids of Formula 4 by reacting the carboxylic acid 4 with thionyl chloride or oxalyl chloride in an inert solvent such as toluene or dichloromethane in the presence of a catalytic amount of N,N-dimethylformamide.

Amines of Formula 2a are typically available from the corresponding nitro compounds of Formula 5 via catalytic hydrogenation of the nitro group. Typical procedures involve reduction with hydrogen in the presence of a metal catalyst such as palladium on carbon or platinum oxide and in hydroxylic solvents such as ethanol and isopropanol. They can also be prepared by reduction with zinc in acetic acid. These procedures are well documented in the chemical literature. R¹ substituents such as alkyl, substituted alkyl and the like can generally be introduced at this stage through the generally preferred method of reductive alkylation of the amine. A commonly employed procedure is to combine the aniline 2a with an aldehyde in the presence of a reducing agent such as sodium cyanoborohydride to produce the Formula 2b compounds where R¹ is alkyl, alkenyl, alkynyl or substituted derivatives thereof.

Compounds of Formula Ic (wherein K is N═C(GR⁶) can be prepared by reaction of imidoylhalides of Formula 6 with sulfur, oxygen and nitrogen nucleophiles of Formula 7. Typically the reactions are conducted in the presence of a base such as a tertiary amine or an alkali metal hydroxide.

Compounds of Formula 6 can be prepared from compounds of Formula Ia by reaction with an appropriate halogenating agent such as phosphorous pentachloride, phosphorous oxychloride, thionyl chloride or triphenyl phosphine and carbon tetrachloride.

Alternatively compounds of Formula Id (wherein K is N═C(SR⁶)) when R⁶ is an alkyl or substituted alkyl group can be prepared from compounds of Formula Ib by reaction with an alkyl halide of Formula 8 optionally in the presence of a base such as a tertiary amine or an alkali metal alkoxide.

Compounds of Formula Ie (wherein K is NR¹SO₂) can be prepared by reacting an amine of Formula 2 with a sulfonyl chloride of Formula 9 in the presence of an acid scavenger. Typical acid scavengers include amine bases such as triethylamine, diisopropylethylamine and pyridine; other scavengers include hydroxides such as sodium and potassium hydroxide and carbonates such as sodium carbonate and potassium carbonate. In certain instances it is useful to use polymer-supported acid scavengers such as polymer-bound diiospropylethylamine and polymer-bound dimethylaminopyridine.

Nitro compounds of Formula 5a (wherein L is C(═O)NR²) can be readily prepared from commercially available 2-nitrobenzoic acids (Scheme 8). Typical methods for amide formation can be applied here. These include direct dehydrative coupling of acids of Formula 10 with amines of Formula 11 using for example DCC, and conversion of the acids to an activated form such as the acid chlorides or anhydrides and subsequent coupling with amines to form amides of Formula 5a. The chemical literature is extensive on this type of reaction. Amides of Formula 5a are readily converted to thioamides of Formula 5b by using commercially available thio transfer reagents such as phosphorus pentasulfide and Lawesson's reagent.

Nitro compounds of Formula 5c (wherein L is C(GR⁶)═N) can be prepared from compounds of Formula 5a via imidoyl halides of Formula 12 by methods similar to those described in Schemes 4 and 5.

Nitro compounds for Formula 5d (wherein L is SO₂NR²) can be prepared from amines of Formula 13 by diazotization with reagents such as sodium nitrite or an alkyl nitrite and reaction with sulfur dioxide in the presence of a copper catalyst (see for instance, Courtin, A. Helv. Chim. Acta, 1976, 59, 379-387) followed by reaction with amines of Formula 11 (see Scheme 8). The synthesis of amines of Formula 13 is well known in the art.

Benzoic acids of Formula 4a (compounds of Formula 4 wherein J is an optionally substituted phenyl ring) are well known in the art. Preparation of certain heterocyclic acids of Formula 4 are described in Schemes 11-16. A variety of heterocyclic acids and general methods for their synthesis may be found in World Patent Application WO 98/57397.

The synthesis of representative pyridine acids (4b) is depicted in Scheme 11. This procedure involves the known synthesis of pyridines from β-ketoesters and 4-aminobutenones (17). Substituent groups R⁵(c) and R⁵(d) include e.g. alkyl and haloalkyl.

The synthesis of representative pyrimidine acids (4c) is depicted in Scheme 12. This procedure involves the known synthesis of pyrimidines from vinylidene-β-ketoesters (20) and amidines. Substituent groups R⁵(c) and R⁵(d) include e.g. alkyl and haloalkyl.

Syntheses of representative pyrazole acids (4d-4g) are depicted in Schemes 13-16. The synthesis of 4d in Scheme 13 involves as the key step introduction of the R⁵(c) substituent via alkylation of the pyrazole. The alkylating agent R⁵(c)-Lg (wherein Lg is a leaving group such as Cl, Br, I, sulfonates such as p-toluenesulfonate or methanesulfonate or sulfates such as —SO₂OR⁵(c)) includes R⁵(c) groups such as C₁-C₆ alkyl, C₂-C₆ alkenyl, C₂-C₆ alkynyl, C₃-C₆ cycloalkyl, C₁-C₆ haloalkyl, C₂-C₆ haloalkenyl, C₂-C₆ haloalkynyl, C₃-C₆ halocycloalkyl, C₂-C₆ alkylcarbonyl, C₂-C₆ alkoxycarbonyl, C₃-C₈ dialkylaminocarbonyl, C₃-C₆ trialkylsilyl; or phenyl, benzyl, benzoyl, 5- or 6-membered heteroaromatic ring or an aromatic 8-, 9- or 10-membered fused heterobicyclic ring system, each ring or ring system optionally substituted. Oxidation of the methyl group affords the pyrazole carboxylic acid. Some of the more preferred R⁵(d) groups include haloalkyl.

Some pyrazole acids of Formula 4d may be prepared via metallation and carboxylation of pyrazoles of Formula 26 as the key step (Scheme 14). The R⁵(c) group is introduced in a manner similar to that of Scheme 13, i.e. via alkylation with a R⁵(c) alkylating agent. Representative R⁵(d) groups include e.g. cyano and haloalkyl.

This procedure is particularly useful for preparing 1-(2-pyridinyl)pyrazolecarboxylic acids of Formula 4e, related to preferred moiety J-5 wherein R⁵ is a substituted 2-pyridinyl ring, as shown in Scheme 15. Reaction of a pyrazole of Formula 27 with a 2,3-dihalopyridine of Formula 23 affords good yields of the 1-pyridinylpyrazole of Formula 28 with good specificity for the desired regiochemistry. Metallation of 28 with lithium diisopropylamide (LDA) followed by quenching of the lithium salt with carbon dioxide affords the 1-(2-pyridinyl)pyrazolecarboxylic acid of Formula 4e.

Other pyrazoles of Formula 4d can be prepared via reaction of an optionally substituted phenyl hydrazine of Formula 30 with a pyruvate of Formula 29 to yield pyrazole esters of Formula 31 (Scheme 16). Hydrolysis of the ester affords the pyrazole acids 4d. This procedure is particularly useful for the preparation of compounds where R⁵(c) is optionally substituted phenyl and R⁵(d) is haloalkyl.

Pyrazole acids of Formula 4d can also be prepared via 3+2 cycloaddition of an appropriately substituted nitrilimine of Formula 32 with either substituted propiolates of Formula 33 or acrylates of Formula 34 (Scheme 17). Cycloaddition with acrylates requires additional oxidation of the intermediate pyrazoline to the pyrazole. Hydrolysis of the ester of Formula 31 affords the pyrazole acids 4d. Preferred iminohalides for this reaction include the trifluoromethyl iminochloride (35) and the iminodibromide (36). Compounds such as 35 are known (J. Heterocycl. Chem. 1985, 22(2), 565-8). Compounds such as 36 are available by known methods (Tetrahedron Letters 1999, 40, 2605). These procedures are particularly useful for the preparation of compounds where R⁵(c) is optionally substituted phenyl and R⁵(d) is haloalkyl or bromo.

The starting pyrazoles of Formula 25 are known compounds or can be prepared according to known methods. The pyrazole of Formula 25a (the compound of Formula 25 wherein R⁵(d) is CF₃) can be prepared by literature procedures (J. Fluorine Chem. 1991, 53(1), 61-70). The pyrazoles of Formula 25b (compounds of Formula 25 wherein R⁵(d) is Cl or Br) can be prepared by literature procedures (Chem. Ber. 1966, 99(10), 33507). A useful alternative method for the preparation of compound 25b is depicted in Scheme 18. Metallation of the sulfamoyl pyrazole of Formula 37 with n-butyllithium followed by direct halogenation of the anion with either hexachloroethane (for R⁵(d) being Cl) or 1,2-dibromotetrachloroethane (for R⁵(d) being Br) affords the halogenated derivatives of Formula 38a. Removal of the sulfamoyl group with trifluoroacetic acid (TFA) at room temperature proceeds cleanly and in good yield to afford the pyrazoles of Formula 25c. One skilled in the art will recognize that Formula 25c is a tautomer of Formula 25b.

The suitable base can be, for example but not limitation, sodium hydride, potassium t-butoxide, dimsyl sodium (CH₃S(O)CH₂ ⁻Na⁺), alkali metal (such as lithium, sodium or potassium) carbonates or hydroxides, tetraalkyl (such as methyl, ethyl or butyl)ammonium fluorides or hydroxides, or 2-tert-butylimino-2-diethylamino-1,3-dimethyl-perhydro-1,3,2-diazapliosphonine. The suitable organic solvent can be, for example but not limitation, acetone, acetonitrile, tetrahydrofuran, dichloromethane, dimethylsulfoxide, or N,N-dimethylformamide. The cyclization reaction is usually conducted in a temperature range from about 0 to 120° C. The effects of solvent, base, temperature and addition time are all interdependent, and choice of reaction conditions is important to minimize the formation of byproducts. A preferred base is tetrabutylammonium fluoride.

Dehydration of the compound of Formula 39 to give the compound of Formula 40, followed by converting the carboxylic ester function to carboxylic acid, affords the compound of Formula 4f. The dehydration is effected by treatment with a catalytic amount of a suitable acid. This catalytic acid can be, for example but not limitation, sulfuric acid. The reaction is generally conducted using an organic solvent. As one skilled in the art will realize, dehydration reactions may be conducted in a wide variety of solvents in a temperature range generally between about 0 and 200° C., more preferably between about 0 and 100° C.). For the dehydration in the method of Scheme 19, a solvent comprising acetic acid and temperatures of about 65° C. are preferred. Carboxylic ester compounds can be converted to carboxylic acid compounds by numerous methods including nucleophilic cleavage under anhydrous conditions or hydrolytic methods involving the use of either acids or bases (see T. W. Greene and P. G. M. Wuts, Protective Groups in Organic Synthesis, 2nd ed., John Wiley & Sons, Inc., New York, 1991, pp. 224-269 for a review of methods). For the method of Scheme 19, base-catalyzed hydrolytic methods are preferred. Suitable bases include alkali metal (such as lithium, sodium or potassium) hydroxides. For example, the ester can be dissolved in a mixture of water and an alcohol such as ethanol. Upon treatment with sodium hydroxide or potassium hydroxide, the ester is saponified to provide the sodium or potassium salt of the carboxylic acid. Acidification with a strong acid, such as hydrochloric acid or sulfuric acid, yields the carboxylic acid of Formula 4f. The carboxylic acid can be isolated by methods known to those skilled in the art, including crystallization, extraction and distillation.

One skilled in the art will recognize that this reaction may require catalysis by an optional acid and may also require elevated temperatures depending on the molecular substitution pattern of the hydrazone of Formula 43. Reaction of the hydrazone of Formula 43 with the compound of Formula 44 in a suitable organic solvent such as, for example but not limitation, dichloromethane or tetrahydrofuran in the presence of an acid scavenger such as triethylamine provides the compound of Formula 38. The reaction is usually conducted at a temperature between about 0 and 100° C.

The acid, when used, should be used in greater than 0.1 equivalents versus the compound of Formula 45. To obtain complete conversion, one to five equivalents of acid can be used. The preferred oxidant is potassium persulfate and the oxidation is preferably carried out in the presence of sulfuric acid.

Optionally, an organic base, such as triethylamine, pyridine, N,N-dimethylaniline or the like, can be added. Addition of a catalyst, such as N,N-dimethylformamide, is also an option. Preferred is the process in which the solvent is acetonitrile and a base is absent. Typically, neither a base nor a catalyst is required when acetonitrile solvent is used. The preferred process is conducted by mixing the compound of Formula 47 in acetonitrile. The halogenating reagent is then added over a convenient time, and the mixture is then held at the desired temperature until the reaction is complete. The reaction temperature is typically between 20° C. and the boiling point of acetonitrile, and the reaction time is typically less than 2 hours. The reaction mass is then neutralized with an inorganic base, such as sodium bicarbonate, sodium hydroxide and the like, or an organic base, such as sodium acetate. The desired product, a compound of Formula 45, can be isolated by methods known to those skilled in the art, including crystallization, extraction and distillation.

Alternatively, compounds of Formula 45 wherein R¹⁰ is Br or Cl can be prepared by treating the corresponding compounds of Formula 45 wherein R¹⁰ is a different halogen (e.g., Cl for making Formula 45 wherein R¹⁰ is Br) or a sulfonate group such as p-toluenesulfonate with hydrogen bromide or hydrogen chloride, respectively. By this method the R¹⁰ halogen or sulfonate substituent on the Formula 45 starting compound is replaced with Br or Cl from hydrogen bromide or hydrogen chloride, respectively. The reaction is conducted in a suitable solvent such as dibromomethane, dichloromethane or acetonitrile. The reaction can be conducted at or near atmospheric pressure or above atmospheric pressure in a pressure vessel. When R¹⁰ in the starting compound of Formula 45 is a halogen such as Cl, the reaction is preferably conducted in such a way that the hydrogen halide generated from the reaction is removed by sparging or other suitable means. The reaction can be conducted between about 0 and 100° C., most conveniently near ambient temperature (e.g., about 10 to 40° C.), and more preferably between about 20 and 30° C. Addition of a Lewis acid catalyst (such as aluminum tribromide for preparing Formula 45 wherein R¹⁰ is Br) can facilitate the reaction. The product of Formula 45 is isolated by the usual methods known to those skilled in the art, including extraction, distillation and crystallization.

Starting compounds of Formula 45 wherein R¹⁰ is Cl or Br can be prepared from corresponding compounds of Formula 47 as already described. Starting compounds of Formula 45 wherein R¹⁰ is a sulfonate group can likewise be prepared from corresponding compounds of Formula 47 by standard methods such as treatment with a sulfonyl chloride (e.g., p-toluenesulfonyl chloride) and base such as a tertiary amine (e.g., triethylamine) in a suitable solvent such as dichloromethane.

Pyrazolecarboxylic acids of Formula 4h wherein R¹⁰ is OCH₂CF₃ can be prepared by the method outlined in Scheme 23. In this method, instead of being halogenated as shown in Scheme 22, the compound of Formula 47 is oxidized to the compound of Formula 48. The reaction conditions for this oxidation are as already described for the conversion of the compound of Formula 45 to the compound of Formula 46 in Scheme 21.

The compound of Formula 48 is then alkylated to form the compound of Formula 50 by contact with an alkylating agent CF₃CH₂Lg (49) in the presence of a base. In the alkylating agent 49, Lg is a nucleophilic reaction leaving group such as halogen (e.g., Br, I), OS(O)₂CH₃ (methanesulfonate), OS(O)₂CF₃, OS(O)₂Ph-p-CH₃ (p-toluenesulfonate), and the like; methanesulfonate works well. The reaction is conducted in the presence of at least one equivalent of a base. Suitable bases include inorganic bases, such as alkali metal (such as lithium, sodium or potassium) carbonates and hydroxides, and organic bases, such as triethylamine, diisopropylethylamine and 1,8-diazabicyclo[5.4.0]undec-7-ene. The reaction is generally conducted in a solvent, which can comprise alcohols, such as methanol and ethanol, halogenated alkanes, such as dichloromethane, aromatic solvents, such as benzene, toluene and chlorobenzene, ethers, such as tetrahydrofuran, and polar aprotic solvents, such as acetonitrile, N,N-dimethylformamide, and the like. Alcohols and polar aprotic solvents are preferred for use with inorganic bases. Potassium carbonate as base and acetonitrile as solvent are preferred. The reaction is generally conducted between about 0 and 150° C., with most typically between ambient temperature and 100° C. The product of Formula 50 can be isolated by conventional techniques such as extraction. The ester of Formula 50 can then be converted to the carboxylic acid of Formula 4h by the methods already described for the conversion of Formula 40 to Formula 4f in Scheme 19.

wherein R⁸ is C₁-C₄ alkyl, and Lg is a leaving group.

Compounds of Formula 47 can be prepared from compounds of Formula 41 (Scheme 20) as outlined in Scheme 24.

wherein R¹³ is C₁-C₄ alkyl.

In this method, a hydrazine compound of Formula 41 is contacted with a compound of Formula 51 (a fumarate ester or maleate ester or a mixture thereof may be used) in the presence of a base and a solvent. The base is typically a metal alkoxide salt, such as sodium methoxide, potassium methoxide, sodium ethoxide, potassium ethoxide, potassium tert-butoxide, lithium tert-butoxide, and the like. Greater than 0.5 equivalents of base versus the compound of Formula 51 should be used, preferably between 0.9 and 1.3 equivalents. Greater than 1.0 equivalents of the compound of Formula 108 should be used, preferably between 1.0 to 1.3 equivalents. Polar protic and polar aprotic organic solvents can be used, such as alcohols, acetonitrile, tetrahydrofuran, N,N-dimethylformamide, dimethyl sulfoxide and the like. Preferred solvents are alcohols such as methanol and ethanol. It is especially preferred that the alcohol be the same as that making up the fumarate or maleate ester and the alkoxide base. The reaction is typically conducted by mixing the compound of Formula 108 and the base in the solvent. The mixture can be heated or cooled to a desired temperature and the compound of Formula 98 added over a period of time. Typically reaction temperatures are between 0° C. and the boiling point of the solvent used. The reaction may be conducted under greater than atmospheric pressure in order to increase the boiling point of the solvent. Temperatures between about 30 and 90° C. are generally preferred. The addition time can be as quick as heat transfer allows. Typical addition times are between 1 minute and 2 hours. Optimum reaction temperature and addition time vary depending upon the identities of the compounds of Formula 98 and Formula 51. After addition, the reaction mixture can be held for a time at the reaction temperature. Depending upon the reaction temperature, the required hold time may be from 0 to 2 hours. Typical hold times are 10 to 60 minutes. The reaction mass then can be acidified by adding an organic acid, such as acetic acid and the like, or an inorganic acid, such as hydrochloric acid, sulfuric acid and the like. Depending on the reaction conditions and the means of isolation, the —CO₂R¹³ function on the compound of Formula 47 may be hydrolyzed to —CO₂H; for example, the presence of water in the reaction mixture can promote such hydrolysis. If the carboxylic acid (—CO₂H) is formed, it can be converted back to —CO₂R¹³ wherein R¹³ is C₁-C₄ alkyl using esterification methods well-known in the art. The desired product, a compound of Formula 47, can be isolated by methods known to those skilled in the art, such as crystallization, extraction or distillation.

Formylation of the pyrrole 69 to provide the aldehyde of Formula 70 can be accomplished by using standard Vilsmeier-Haack formylation conditions, such as N,N-dimethylformamide (DMF) and phosphorus oxychloride. Halogenation of the compound of Formula 70 with N-halosuccinimides (NXS) such as N-chlorosuccinimide or N-bromosuccinimide occurs preferentially at the 4-position of the pyrrole ring.

3-Cl-2-pyridyl Formulation/Utility

Compounds of this invention will generally be used as a formulation or composition with an agriculturally suitable carrier comprising at least one of a liquid diluent, a solid diluent or a surfactant. The formulation or composition ingredients are selected to be consistent with the physical properties of the active ingredient, mode of application and environmental factors such as soil type, moisture and temperature. Useful formulations include liquids such as solutions (including emulsifiable concentrates), suspensions, emulsions (including microemulsions and/or suspoemulsions) and the like which optionally can be thickened into gels. Useful formulations further include solids such as dusts, powders, granules, pellets, tablets, films, and the like which can be water-dispersible (“wettable”) or water-soluble. Active ingredient can be (micro)encapsulated and further formed into a suspension or solid formulation; alternatively the entire formulation of active ingredient can be encapsulated (or “overcoated”). Encapsulation can control or delay release of the active ingredient. Sprayable formulations can be extended in suitable media and used at spray volumes from about one to several hundred liters per hectare. High-strength compositions are primarily used as intermediates for further formulation.

The formulations will typically contain effective amounts of active ingredient, diluent and surfactant within the following approximate ranges that add up to 100 percent by weight. Weight Percent Active Ingredient Diluent Surfactant Water-Dispersible and Water-soluble 5-90 0-94 1-15 Granules, Tablets and Powders.

Solid diluents include, for example, clays such as bentonite, montmorillonite, attapulgite and kaolin, starch, sugar, silica, talc, diatomaceous earth, urea, calcium carbonate, sodium carbonate and bicarbonate, and sodium sulfate. Liquid diluents include, for example, water, N,N-dimethylformamide, dimethyl sulfoxide, N-alkylpyrrolidone, ethylene glycol, polypropylene glycol, paraffins, alkylbenzenes, alkylnaphthalenes, oils of olive, castor, linseed, tung, sesame, corn, peanut, cotton-seed, soybean, rape-seed and coconut, fatty acid esters, ketones such as cyclohexalnone, 2-heptanone, isophorone and 4-hydroxy-4-methyl-2-pentanone, and alcohols such as methanol, cyclohexanol, decanol and tetrahydrofurfuryl alcohol.

Solutions, including emulsifiable concentrates, can be prepared by simply mixing the ingredients. Dusts and powders can be prepared by blending and, usually, grinding as in a hammer mill or fluid-energy mill. Suspensions are usually prepared by wet-milling; see, for example, U.S. Pat. No. 3,060,084. Granules and pellets can be prepared by spraying the active material upon preformed granular carriers or by agglomeration techniques. See Browning, “Agglomeration”, Chemical Engineering, Dec. 4, 1967, pp 14748, Perry's Chemical Engineer's Handbook, 4th Ed., McGraw-Hill, New York, 1963, pages 8-57 and following, and PCT Publication WO 91/13546. Pellets can be prepared as described in U.S. Pat. No. 4,172,714. Water-dispersible and water-soluble granules can be prepared as taught in U.S. Pat. No. 4,144,050, U.S. Pat. No. 3,920,442 and DE 3,246,493. Tablets can be prepared as taught in U.S. Pat. No. 5,180,587, U.S. Pat. No. 5,232,701 and U.S. Pat. No. 5,208,030.

Compounds of this invention are characterized by favorable metabolic and/or soil residual patterns and exhibit activity controlling a spectrum of agronomic and non-agronomic invertebrate pests. (In the context of this disclosure “invertebrate pest control” means inhibition of invertebrate pest development (including mortality) that causes significant reduction in feeding or other injury or damage caused by the pest; related expressions are defined analogously.) As referred to in this disclosure, the term “invertebrate pest” includes arthropods, gastropods and nematodes of economic importance as pests. The term “arthropod” includes insects, mites, spiders, scorpions, centipedes, millipedes, pill bugs and symphylans. The term “gastropod” includes snails, slugs and other Stylommatophora. The term “nematode” includes all of the helminths, such as: roundworms, heartworms, and phytophagous nematodes (Nematoda), flukes (Tematoda), Acanthocephala, and tapeworms (Cestoda). Those skilled in the art will recognize that not all compounds are equally effective against all pests. Compounds of this invention display activity against economically important agronomic and nonagronomic pests. The term “agronomic” refers to the production of field crops such as for food and fiber and includes the growth of cereal crops (e.g., wheat, oats, barley, rye, rice, maize), soybeans, vegetable crops (e.g., lettuce, cabbage, tomatoes, beans), potatoes, sweet potatoes, grapes, cotton, and tree fruits (e.g., pome fruits, stone fruits and citrus fruits). The term “nonagronomic” refers to other horticultural (e.g., forest, greenhouse, nursery or ornamental plants not grown in a field), public (human) and animal health, domestic and commercial structure, household, and stored product applications or pests. For reason of invertebrate pest control spectrum and economic importance, protection (from damage or injury caused by invertebrate pests) of agronomic crops of cotton, maize, soybeans, rice, vegetable crops, potato, sweet potato, grapes and tree fruit by controlling invertebrate pests are preferred embodiments of the invention.

Thus, compositions of the present invention can further comprise a biologically effective amount of at least one additional invertebrate pest control compound or agent having a similar spectrum of control but a different mode of action. Contacting a plant genetically modified to express a plant protection compound (e.g., protein) or the locus of the plant with a biologically effective amount of a compound of invention can also provide a broader spectrum of plant protection and be advantageous for resistance management.

Invertebrate pests are controlled in agronomic and nonagronomic applications by applying one or more of the compounds of this invention, in an effective amount, to the environment of the pests including the agronomic and/or nonagronomic locus of infestation, to the area to be protected, or directly on the pests to be controlled. Thus, the present invention further comprises a method for the control of an invertebrate pest in agronomic and/or nonagronomic applications, comprising contacting the invertebrate pest or its environment with a biologically effective amount of one or more of the compounds of the invention, or with a composition comprising at least one such compound or a composition comprising at least one such compound and an effective amount of at least one additional biologically active compound or agent. Examples of suitable compositions comprising a compound of the invention and an effective amount of at least one additional biologically active compound or agent include granular compositions wherein the additional biologically active compound or agent is present on the same granule as the compound of the invention or on granules separate from those of the compound of this invention.

A preferred method of contact is by spraying. Alternatively, a granular composition comprising a compound of the invention can be applied to the plant foliage or the soil. Compounds of this invention are also effectively delivered through plant uptake by contacting the plant with a composition comprising a compound of this invention applied as a soil drench of a liquid formulation, a granular formulation to the soil, a nursery box treatment or a dip of transplants. Compounds are also effective by topical application of a composition comprising a compound of this invention to the locus of infestation. Other methods of contact include application of a compound or a composition of the invention by direct and residual sprays, aerial sprays, gels, seed coatings, microencapsulations, systemic uptake, baits, eartags, boluses, foggers, fumigants, aerosols, dusts and many others. The compounds of this invention may also be impregnated into materials for fabricating invertebrate control devices (e.g. insect netting).

The compounds of this invention can be incorporated into baits that are consumed by the invertebrates or within devices such as traps and the like. Granules or baits comprising between 0.01-5% active ingredient, 0.05-10% moisture retaining agent(s) and 40-99% vegetable flour are effective in controlling soil insects at very low application rates, particularly at doses of active ingredient that are lethal by ingestion rather than by direct contact.

The compounds of this invention can be applied in their pure state, but most often application will be of a formulation comprising one or more compounds with suitable carriers, diluents, and surfactants and possibly in combination with a food depending on the contemplated end use. A preferred method of application involves spraying a water dispersion or refined oil solution of the compounds. Combinations with spray oils, spray oil concentrations, spreader stickers, adjuvants, other solvents, and synergists such as piperonyl butoxide often enhance compound efficacy.

The rate of application required for effective control (i.e. “biologically effective amount”) will depend on such factors as the species of invertebrate to be controlled, the pest's life cycle, life stage, its size, location, time of year, host crop or animal, feeding behavior, mating behavior, ambient moisture, temperature, and the like. Under normal circumstances, application rates of about 0.01 to 2 kg of active ingredient per hectare are sufficient to control pests in agronomic ecosystems, but as little as 0.0001 kg/hectare may be sufficient or as much as 8 kg/hectare may be required. For nonagronomic applications, effective use rates will range from about 1.0 to 50 mg/square meter but as little as 0.1 mg/square meter may be sufficient or as much as 150 mg/square meter may be required. One skilled in the art can easily determine the biologically effective amount necessary for the desired level of invertebrate pest control.

The following TESTS demonstrate the control efficacy of compounds of this invention on specific pests. “Control efficacy” represents inhibition of invertebrate pest development (including mortality) that causes significantly reduced feeding. The pest control protection afforded by the compounds is not limited, however, to these species. See Index Tables A and B for compound descriptions.

BIOLOGICAL EXAMPLES OF THE INVENTION

For evaluating control of diamondback moth (Plutella xylostella) the test unit consisted of a small open container with a 12-14-day-old radish plant inside. This was pre-infested with 10-15 neonate larvae on a piece of insect diet by use of a core sampler to remove a plug from a sheet of hardened insect diet having many larvae growing on it and transfer the plug containing larvae and diet to the test unit. The larvae moved onto the test plant as the diet plug dried out.

Test compounds were formulated using a solution containing 10% acetone, 90% water and 300 ppm X-77(D Spreader Lo-Foam Formula non-ionic surfactant containing alkylarylpolyoxyethylene, free fatty acids, glycols and isopropanol (Loveland Industries, Inc.), unless otherwise indicated. The formulated compounds were applied in 1 mL of liquid through a SUJ2 atomizer nozzle with ⅛ JJ custom body (Spraying Systems Co.) positioned 1.27 cm (0.5 inches) above the top of each test unit. All experimental compounds in this screen were sprayed at 250 ppm (or lower) and replicated three times. After spraying of the formulated test compound, each test unit was allowed to dry for 1 hour and then a black, screened cap was placed on top. The test units were held for 6 days in a growth chamber at 25° C. and 70% relative humidity. Plant feeding damage was then visually assessed.

Of the compounds tested, the following provided excellent levels of plant protection (20% orless feeding damage): 1*, B3*, C2**, C5* andC6*.

Test B

For evaluating control of fall armyworm (Spodoptera frugiperda) the test unit consisted of a small open container with a 45-day-old corn (maize) plant inside. This was pre-infested with 10-15 1-day-old larvae on a piece of insect diet by use of a core sampler as described for Test A.
